This blog summarizes what I have found interesting or not-obvious about the Sun's open source enterprise application server called GlassFish. If you think, any of the info in this blog is not precise or just incorrect, feel free to comment.

Version 2.1 of GlassFish is the final version that implements Java EE 5. Version 3.0 of GlassFish is the first one that implements Java EE 6. It's a preview, but ready for production.

Server Domain: a new concept introduced into GlassFish that means one or more server instances that can be managed as a whole by an administrator. For developer, domain=server instance. For administrator, it can comprise of multiple, clustered server instances. Each domain, even if all domains are local, runs in its own JVM (there is also one JVM instance associated with the server administration/control, it seems). More info.
